<1. Embodiment of the present disclosure>
[1.1. Overview]
First, an outline of an embodiment of the present disclosure will be described. The embodiment of the present disclosure is premised on that a power storage device provided with a secondary battery is installed in a residence or a facility, and a plurality of homes or facilities in which the power storage device is installed form one community. The storage devices are connected by a communication line and a power line.

FIG. 1 is an explanatory view showing a configuration example of a power system 1 for describing an embodiment of the present disclosure. FIG. 1 shows a community 2 formed by a plurality of residences and facilities in which power storage devices 200a to 200n are installed, and central control device 10 for controlling power accommodation for power storage devices 200a to 200n. There is.

Central controller 10 includes a power distribution generation unit 11, a power interchange pair generation unit 12, and a power interchange control unit 13. Power distribution generation unit 11 calculates the power distribution of each of target power storage devices 200a to 200n. The power accommodation pair generation unit 12 generates a pair of storage devices for storing power based on the power distribution of the target power storage devices 200a to 200n generated by the power distribution generation unit 11. The power interchange control unit 13 sends a predetermined control signal to the pair of storage devices that interchange power generated by the power interchange pair generation unit 12. The control signal is sent to the storage device via the communication line 20. The control signal may be sent from the central control unit 10 to each of the power storage devices 200a to 200n by wire through the communication line 20, or may be sent to each of the power storage devices 200a to 200n wirelessly.

Power storage devices 200a to 200n are mutually connected through communication line 20 and power line 30. Here, the configuration of the power storage device 200a will be described by taking the power storage device 200a as an example.

Power storage device 200a is configured to include DCDC converter control unit 210a, DCDC converter 220, and storage battery 230a.

The DCDC converter control unit 210 a controls the operation of the DCDC converter 220. Here, the DCDC converter control unit 210a performs setting of the DCDC converter 220 based on the control signal sent from the power interchange control unit 13. The setting of the DCDC converter 220 performed by the DCDC converter control unit 210a includes, for example, setting of a voltage to the power line 30, setting of current to the power line 30, supply destination of power, supply time of power, and the like.

DCDC converter 220 a performs conversion of DC power between storage battery 230 a and power line 30. The DCDC converter 220a is set variously by the DCDC converter control unit 210a.

The storage battery 230a is, for example, a lithium ion secondary battery, a sodium-sulfur battery, or other secondary battery. The storage battery 230a can store electric power generated by a power generation device that generates electric power by solar light, solar heat, wind power, etc. (not shown).

For example, when central control device 10 determines that power exchange is to be performed between power storage device 200a and power storage device 200b,

power storage devices

200a, 200b transmit power line 30 according to a control signal output from central control device 10. Accommodation of power through

When the power system 1 is configured as described above, the central control unit 10 directly controls the power storage devices 200a to 200n. At this time, the central control unit 10 determines a pair of storage devices to which power is to be transferred according to an algorithm. However, when power system 1 is configured in this manner, it is difficult to mix a plurality of algorithms and to reflect the preference of the owner of each power storage device.

Therefore, a method may be considered in which each power storage device is indirectly controlled by distributing control data from the central control device 10 instead of directly controlling each power storage device with a control signal from the central control device 10. By indirectly controlling each power storage device according to the control data, it becomes easy to mix a plurality of algorithms or to reflect the preference of the owner of each power storage device.

FIG. 2 is an explanatory view showing a configuration example of the power system 1 for describing the embodiment of the present disclosure. FIG. 2 shows a community 2 formed by a plurality of residences and facilities in which power storage devices 200a to 200n are installed, and central control device 10 for controlling power accommodation to power storage devices 200a to 200n. There is.

Central control device 10 includes a power distribution generation unit 11, a control data generation unit 14, and a control data update unit 15. Control data generation unit 14 generates control data for controlling the power storage device to which power is transferred, based on the power distribution of each of target power storage devices 200a to 200n generated by power distribution generation unit 11. Control data update unit 15 provides control data generated by control data generation unit 14 to power storage devices 200a to 200n through communication line 20.

Power storage device 200a is configured to include control data storage unit 205a, DCDC converter control unit 210a, DCDC converter 220a, and storage battery 230a. A difference from power storage device 200a shown in FIG. 1 is that power storage device 200a shown in FIG. 2 holds control data storage unit 205a. The control data storage unit 205a stores one or more control data for controlling the operation of the DCDC converter 220a. The DCDC converter control unit 210a controls the operation of the DCDC converter 220a using the control data stored in the control data storage unit 205a. When controlling the operation of DCDC converter 220a, DCDC converter control unit 210a determines whether to use control data provided from central control device 10 or to use control data uniquely generated in power storage device 200a. That is, the operation of power storage device 200a does not necessarily have to follow the intention of central control device 10.

Thus, in the power system 1 shown in FIG. 2, the operation of each of the storage devices 200a to 200n follows the intention of the central control device 10 as well as the intention of the user of each of the storage devices 200a to 200n.

However, for example, when there is a disaster such as an earthquake, a typhoon, or a fire, etc., the supply of commercial power to community 2 is interrupted, or it is desired to concentrate on a specific power storage device to exchange power from other power storage devices. The case is, of course, also assumed. In this case, the storage devices 200a to 200n are required to operate in accordance with the intention of the central control device 10, not according to the intentions of the users of the storage devices 200a to 200n.

[1.2. Configuration example]
FIG. 3 is an explanatory view showing a configuration example of the power system 1 according to the embodiment of the present disclosure. FIG. 3 shows a community 2 formed by a plurality of residences and facilities in which power storage devices 200a to 200n are installed, and central control device 100 for controlling power accommodation to power storage devices 200a to 200n. There is.

As shown in FIG. 3, the central control device 100 according to the embodiment of the present disclosure includes the power accommodation condition selection unit 101, the disaster control data generation unit 102, the overall optimum control data generation unit 103, and the individual control. A data generation unit 104, a control data storage unit 105, a control data selection unit 106, a control data update unit 107, a disaster determination unit 108, and a community common rule 109 are included.

Power interchange condition selection unit 101 selects, for the user of each of power storage devices 200a to 200n, what kind of power accommodation should be performed, and whether to perform optimum power accommodation (total optimum power accommodation) for the entire community 2 Let

The disaster control data generation unit 102 includes information of a specific power storage device (referred to as a priority power storage device), which is described in the community common rule 109 and provided in a facility where power storage is prioritized at the time of disaster occurrence such as earthquake, typhoon, or fire. To generate disaster control data for power transmission to the priority storage device. The disaster control data generation unit 102 records the generated disaster control data in the control data storage unit 105.

The overall optimum control data generation unit 103 generates, for example, overall optimum control data which is control data for realizing power interchange that maximizes the amount of renewable energy generation of the entire community 2. That is, overall optimum control data generation unit 103 is generated for each of power storage devices 200a to 200n used by a user who wants to implement overall optimum power accommodation. The overall optimum control data generation unit 103 records the generated overall optimum control data in the control data storage unit 105.

The individual control data generation unit 104 confirms, for example, the preference of the user such as a mode of actively storing and a mode of actively discharging, and generates individual control data which is control data for realizing the control. That is, individual control data generation unit 104 is generated for each of power storage devices 200a to 200n used by a user who wants to execute power interchange individually. The individual control data generation unit 104 records the generated individual control data in the control data storage unit 105.

The control data storage unit 105 records three types of control data: disaster control data, overall optimum control data, and individual control data. FIG. 4 is an explanatory view showing an example of control data recorded in the control data storage unit 105. As shown in FIG. FIG. 4 shows that individual control data, overall optimum control data, and disaster control data corresponding to each power storage device in community 2 are recorded in control data storage unit 105. In the example shown in FIG. 4, overall optimum control data does not exist in power storage devices 2 and 3. In FIG. 4, it is indicated by “N / A” that there is no overall optimum control data in power storage devices 2 and 3. That is, it is shown in FIG. 4 that power storage devices 2 and 3 are not targets of overall optimum power interchange.

Control data selection unit 106 selects control data to be provided to power storage devices 200a to 200n from among the control data stored in control data storage unit 105. Specifically, the control data selection unit 106 selects the control data recorded in the control data storage unit 105 with priority based on the presence or absence of the disaster determination and the presence or absence of the overall optimum control data, It is transmitted to the updating unit 107. The priority may be, for example, in the order of disaster control data, overall optimum control data, and individual control data. The selection process of control data by the control data selection unit 106 will be described in detail later.

Control data update unit 107 provides the control data selected by control data selection unit 106 to each of power storage devices 200a to 200n. For example, when control data selection unit 106 selects overall optimum control data (for power storage device 200a) for power storage device 200a and individual control data for power storage device 200b, the control data is selected. Update unit 107 provides overall optimum control data (for power storage device 200a) to power storage device 200a, and provides individual control data to power storage device 200b.

The disaster determination unit 108 determines, by the system administrator of the power system 1, whether or not the information indicating that the supply of power has been interrupted due to the occurrence of a disaster or that the supply of power has become unstable has been input. At the time of this determination, the disaster determination unit 108 may refer to the disaster determination method described in the community common rule 109. When determining that information indicating that a disaster has occurred is input, the disaster determination unit 108 notifies the control data selection unit 106 that a disaster has occurred. The control data selection unit 106 selects disaster control data from the control data stored in the control data storage unit 105 when receiving notification from the disaster determination unit 108 that a disaster has occurred. Then, the control data selection unit 106 passes the selected disaster control data to the control data update unit 107.

In the present embodiment, whether or not a disaster has occurred is determined by whether or not the information on the occurrence of a disaster is input to the disaster determination unit 108 by the system administrator of the power system 1. It is not limited. For example, whether or not a disaster occurs may be determined based on whether or not the power company has input information indicating that the power supply has become unstable due to the occurrence of a disaster.

The community common rules 109 describe rules for power interchange in the community 2. The form of the community common rule 109 may be any form, may be text data, and may be a predetermined markup language. The community common rule 109 describes, for example, a facility that prioritizes power supply when a disaster occurs, a disaster determination method, and the like. A user who wants to participate in the power system 1 to perform power interchange can make the power interchange possible by agreeing to the community common rule 109.

As a disaster determination method, for example, in the case of having renewable energy and a plurality of power sources such as a commercial power system, when power supply from the commercial power system is interrupted due to a typhoon or the like, it is determined as a disaster. And, if it is determined that the community common rule 109 is a disaster, for example, the minimum of the community 2 is provided by preferentially supplying power to specific facilities such as schools and public halls where it is assumed that the residents will be evacuated. Rules intended to maintain the activities of the group shall be described. For example, when the power storage device 200a is placed in a school, the community common rule 109 indicates that power is preferentially supplied to the power storage device 200a at the time of disaster determination.

When the disaster control data is passed, the control data updating unit 107 forcibly supplies the passed disaster control data to the power storage devices 200a to 200n.

Power storage devices 200a to 200n have the same configuration as that shown in FIG. In other words, power storage devices 200a to 200n implement mutual interchange of power via power line 30 based on control data stored in control data storage units 205a to 205n, respectively.

Then, when disaster control data is transmitted from central control device 100, power storage devices 200a to 200n immediately apply disaster control data and carry out power interchange based on the disaster control data. For example, when disaster control data is provided from central control device 100 to concentrate power storage device 200a and exchange power, storage device 230a reaches a predetermined capacity from other power storage devices 200b to 200n. The DC power is received until the power storage devices 200b to 200n transmit the DC power to the power storage device 200a.

The configuration example of the power system 1 according to the embodiment of the present disclosure has been described above. Subsequently, an operation example of the power system 1 according to the embodiment of the present disclosure will be described.

[1.3. Operation example]
FIG. 5 is an operation example of the power system 1 according to the embodiment of the present disclosure, and is a flowchart illustrating an operation example of the control data selection unit 106 of the central control device 100. Hereinafter, an operation example of the power system 1 according to the embodiment of the present disclosure will be described using FIG. 5.

The control data selection unit 106 first determines whether the disaster determination unit 108 determines that there is a disaster and receives notification of the occurrence of the disaster (step S101).

As a result of the determination in step S101, if notification of the occurrence of a disaster has not been received (No in step S101), control data selection unit 106 subsequently transmits control data storage unit 105 to control data storage unit 105 for the entire optimum control data. It is determined whether it is recorded (step S102).

For a power storage device whose global optimum control data is not recorded in control data storage unit 105 (No at step S102), control data selection unit 106 transmits individual control data to control data update unit 107 (step S103). ). On the other hand, for a power storage device in which overall optimum control data is recorded in control data storage unit 105 (Yes at step S102), control data selection unit 106 transmits overall optimum control data to control data update unit 107. (Step S104).

As a result of the determination in step S101, if the notification indicating the occurrence of a disaster has been received (Yes in step S101), the control data selection unit 106 subsequently acquires disaster control data from the control data storage unit 105 and acquires it. The disaster control data is transmitted to the control data updating unit 107 (step S105).

Thereafter, the control data selection unit 106 stands by at a constant interval (step S106), and returns to the determination process of step S101.

6 and 7 are explanatory diagrams showing examples of selection of control data recorded in the control data storage unit 105. FIG. If notification of the occurrence of a disaster is received, the control data selection unit 106 selects disaster control data from among the control data recorded in the control data storage unit 105 as shown in FIG. The selected disaster control data is provided from control data update unit 107 to each of power storage devices 200a to 200n. On the other hand, if notification of the occurrence of a disaster has been received, as shown in FIG. 7, the control data selection unit 106 selects individual control data or overall optimization from among the control data recorded in the control data storage unit 105. Select control data. The selected individual control data or overall optimum control data is provided from control data update unit 107 to each of power storage devices 200a to 200n.

When the control data selection unit 106 executes a series of operations as shown in FIG. 5, the central control device 100 according to the embodiment of the present disclosure can control the disaster control data when a disaster occurs. Otherwise, normal control data (individual control data or overall optimum control data) can be provided to each of power storage devices 200a to 200n. Then, power storage devices 200a to 200n execute power interchange based on control data provided from central control device 100. In particular, when disaster control data is sent from central control apparatus 100, power storage devices 200a to 200n immediately execute power interchange based on the disaster control data. Accordingly, power storage devices 200a to 200n can perform power interchange such that power is concentrated on a specific power storage device described in the disaster control data.

Next, an example of generation of disaster control data will be described. FIG. 8 is a flowchart showing an example of generation of disaster control data by the disaster control data generation unit 102 of the central control device 100 according to the embodiment of the present disclosure.

First, we explain the premise of the community common rules. Here, as a disaster determination rule, it is determined that the power supply from the commercial power grid is cut off as a disaster. Further, as a rule at the time of disaster, power is preferentially supplied to the

power storage devices

1, 2, 3 among the plurality of power storage devices, and this is a rule for maintaining the minimum function of the community.

If the power supply from the grid is not cut off (No at Step S111), the disaster control data generation unit 102 sets each power storage device to the normal operation mode (Step S112). On the other hand, when the power supply from the grid is cut off (Yes at step S111), the disaster control data generation unit 102 places each storage device in the disaster mode, and controls the

storage devices

1, 2, 3 for charging. The control data at the time of disaster is generated as the control data for discharging the data and the remaining power storage devices (step S113).

Thereafter, the disaster control data generation unit 102 stands by at a constant interval (step S114), and returns to the determination process of step S111.

With the disaster control data generation unit 102 operating in this manner, the central control device 100 according to the embodiment of the present disclosure generates disaster control data to be provided to each power storage device when a disaster occurs. You can do it.

Subsequently, the operation of the power interchange condition selection unit 101 will be described. Power interchange condition selection unit 101 can provide a user interface for causing users of power storage devices 200a to 200n to input a power usage pattern of the power storage device used by themselves. FIG. 9 is an explanatory view showing an example of a user interface provided by the power interchange condition selection unit 101 according to the embodiment of the present disclosure. A user interface 300 provided by the power interchange condition selection unit 101 is shown in FIG. The user interface 300 may be displayed on the screen of each of the power storage devices 200a to 200n, for example, when the user accesses the central control device 100 with a personal computer, a smartphone, a tablet terminal or the like.

When the user opens the pull-down menu of the user interface 300, the power interchange condition selection unit 101 displays a list 301 of pull-down menus. The list 301 includes five options of “recommend”, “use a lot”, “do not use very much”, “use often at night”, and “manual” regarding the power usage pattern. When the user selects one of the options displayed in the list 301, the power interchange condition selection unit 101 generates control data according to the selected option.

Of course, it goes without saying that the power usage pattern provided by the power interchange condition selection unit 101 is not limited to that shown in FIG. Other commonly used patterns during the day, and less frequently used on weekdays, but also frequently used on weekends, may be included as options.

FIG. 10 is a flowchart showing an operation example of the power interchange condition selection unit 101 according to the embodiment of the present disclosure. If the user selects “recommend” from among the options of the power usage pattern displayed in the list 301 (Yes in step S121), the power interchange condition selection unit 101 generates the entire optimum control data as a whole. It notifies the optimum control data generation unit 103 (step S122). If the user does not select “recommend” from the options of the power usage pattern displayed in the list 301 (No at step S121), the power interchange condition selection unit 101 performs individual control to generate individual control data. The data generation unit 104 is notified (step S123).

Subsequently, an operation example of the overall optimum control data generation unit 103 will be described. FIG. 11 is a flowchart showing an operation example of the overall optimum control data generation unit 103 according to the embodiment of the present disclosure. FIG. 11 shows an operation example of the overall optimum control data generation unit 103 for generating the overall optimum control data.

First, among the power storage devices 200a to 200n of each residence, for the power storage device for which “recommend” is selected, the overall optimum control data generation unit 103 determines the current remaining power amount W ₀ of the power storage device and the generated power P _gen . from the predicted _{P con,} the electric storage devices of the residence, after T time (T 1 hour increments between eg 0-24 hours) to predict the remaining battery capacity _{W T} in (step S131). At this time, the power storage device predicts the remaining battery capacity W _T by Equation 1 below.

Then the power storage device, the remaining battery capacity W _T predicted in step S131, the determining whether a value of T which is less than 0 (step S132). In the battery remaining amount _{W T} predicted in step S131, the if the value of T that is less than 0 (step S132, Yes), extracts the value of the T (step S133).

Overall optimal control data generation unit 103 collects the value of T for which W _T <0 for the power storage device for which “recommended” is selected (step S 134). Then, the global optimum control data generation unit 103 arranges the collected T values in ascending order (step S135). _Let T _{chg_1} , T _{chg_2} ,... In ascending order of the collected T values.

On the other hand, followed by the power storage device, in step S132, the remaining battery capacity _{W T} predicted in step S131, it is determined that there is no value of T that is less than 0 (step S132, No), followed by step S131 in the predicted remaining battery capacity _{W T,} it is determined whether a value of T greater than the maximum remaining battery capacity _{W max} (step S136). In the battery remaining amount _{W T} predicted in step S131, the if there is a value of T greater than the battery remaining amount _{W max} (step S136, Yes), extracts the value of the T (step S137).

Overall optimal control data generation unit 103 collects the value of T for which W _T > W _max for the power storage device for which “recommend” is selected (step S 138). Then, the global optimum control data generation unit 103 arranges the collected T values in ascending order (step S139). _Let T _{dchg_1} , T _{dchg_2} ,...

Subsequently overall optimization control data generating unit 103, for each _{T Chg_n} aligned in step S135 (n is an integer of 1 or more), (the n 1 or more integer) _{T Dchg_n} aligned in step S139 is It is determined whether there is any (step S140). It is determined in step _S140, for each _{T _{Chg_n,}} if there is _{T dchg_n} (step S140, Yes), the overall optimal control data generating unit 103 includes a power storage device notifies the _{T _{Chg_n,}} notifies the _{T Dchg_n} Control data for exchanging power with the stored power storage device is generated (step S141). After generating the control data, the overall optimum control data generation unit 103 waits for a predetermined fixed time interval (for example, 15 minutes) (step S142).

FIG. 12 is an example of control data generated by the overall optimum control data generation unit 103. FIG _12, the control data for the power storage device notifies the _{T _{Chg_n,}} and control data for the power storage device notifies the _{T Dchg_n,} are the shown.

Control data to charge the battery is generated (step S152). FIG. 13 shows an example of control data that is positively charged from another power storage device. FIG. 13 shows an example of control data for performing charging and discharging with another power storage device until the target battery remaining amount reaches 90% all day (between 0 o'clock and 24 o'clock). It is done. Of course, the target battery remaining amount is not limited to such an example. Moreover, the charging / discharging destination may be specified.

As a result of the determination in step S151, if "use a lot" is not selected as the power use pattern (step S151, No), next, individual control data generation unit 104 generates individual control data for the power storage device. At this time, it is determined whether or not “do not use very much” selected from the list 301 shown in FIG. 10 as a power use pattern (step S153).

As a result of the determination in step S153, if “not used very much” is selected as the power usage pattern (Yes in step S153), individual control data generation unit 104 causes the power storage device to actively transmit to another power storage device. Control data to generate a static discharge (step S154). FIG. 13 shows an example of control data which is actively discharged to another power storage device. FIG. 13 shows an example of control data for performing charge and discharge with another power storage device until the target battery remaining amount reaches 10% all day (between 0 o'clock and 24 o'clock). It is done. Of course, the target battery remaining amount is not limited to such an example. Moreover, the charging / discharging destination may be specified.

As a result of the determination in step S153, if it is not "do not use very" selected as the power use pattern (step S153, No), next, individual control data generation unit 104 generates individual control data for the power storage device At this time, it is determined whether or not “used frequently at night” is selected from the list 301 shown in FIG. 10 as the power usage pattern (step S155).

As a result of the determination in step S155, if it is determined that the power use pattern is “use often at night” (step S155, Yes), the individual control data generation unit 104 determines that the storage device is connected to another storage device. During the daytime, control data is generated such that the battery is actively discharged and the battery is actively charged at night (step S156). FIG. 13 shows an example of control data that discharges positively during the day and charges positively at night among the other power storage devices. FIG. 13 shows that the target battery remaining amount becomes 10% from 4 o'clock to 17 o'clock, and the target battery remaining amount becomes 90% from 17 o'clock to 4 o'clock with other electric storage devices. An example of control data for performing charge and discharge is shown. Of course, the target battery remaining amount is not limited to such an example. Moreover, the charging / discharging destination may be specified.

As a result of the determination in step S155, if it is determined that “the power usage pattern is not frequently used” (No in step S155), the individual control data generation unit 104 causes the user to generate control data by itself (step S 157).

By operating in this manner, individual control data generation unit 104 can generate control data desired by the user of each power storage device.

As mentioned above, the power usage pattern options may include other commonly used patterns during the day, and less frequently used on weekdays but also frequently used on weekends. In that case, the individual control data generation unit 104 can generate control data corresponding to a pattern frequently used during the day or a pattern not frequently used on weekdays but frequently used on the weekend.
